To all whom 2'6 may concern:

Be it known that I, CARL HJLEIDING, a citizen of the United States of America, and resident of Baltimore, Maryland, have. in vented certain Improvements in Safety Appliances for Window-Gleaners, ofjwhich the following is a specification.

This invention relates toan improv'e d portable device whereby window cleaners, who have to standv during a part of the cleaning operation, on the sill exteriorly 0fthewindow, are protected from serious injury should they lose their foothhold, as will hereinafter fully appear;

In the further description of the said invention which follows, reference is made to the accompanying drawing forming a part hereof, and in which, Figure 1 is a perspective view showing the invention .as applied to-a window frame; and Fig.2 an enlarged partly sectional vview of parts of the apparatus. j v Fig. 3 is a section of Fig. 2 taken on the dotted line wm.

Referring now to the drawing, 1 represents a window sill, and 2 a window frame erected thereon. a J 3 is a portable bar which in order that it can be easily changed in length, is 'preferably made of a tube in three pieces or sec tions a, b and c. v l

The end pieces a and a have each a short solid bar at fastened therein which projects beyond its inner end and is-adapted to enter the central section b, and be fastened by what is usually termed a bayonet connection:

e as shown. 1

4c, 4 are brackets tudinally of the bar 3, and they are fastened when set, by the thumb screws f. "At their adapted to he slid longifree ends the brackets are furnished with pointed thumb screws '9 which are adapted to be forced into the window frame 2.. By

this means the brackets 4 carrying the barv 3 can be held at any desired height, and secured. The hubs h of the brackets are fitted is buckled around the waist of the cleaner.

Each rope is provided with a plate 9 which has a succession of holes through which the rope passes so as to take up the ropes in case of their being too long,

By means of the brackets with the thumb screws which can be screwed into the window frame, the safety device can be placed in any vertical position instead of at all times resting on the window sill.

I claim as my invention:

In a safety appliance forwindow cleaners, the combination of the following elements, to wit: a bar, a pair of brackets each having a tubular hub provided with arope loop, said brackets being 'adaptedto be slid longitudinally of said bar, means for fastening each of said brackets to said bar, a p'ointe thumb screw threaded in the upper end of each bracket for engagement with the window frame,- ropes looped with the loops of said. brackets and snap hooks fastened to said ropes or' connection with a strap buckled around the vwaist of the operator, substantially as set forth, x
